Abstract

A redox transmetallation/ligand exchange reaction between Al metal, Hg(C6F5)(2) and 3,5-di-tert-butyl-pyrazole (tBu(2)pzH) in tetrahydrofuran (thf) yields [Al(tBu(2)pz)(3)(thf)] in which the six coordinate aluminium atom has two eta(2)- and one eta(1)-tBu(2)pz ligands. By contrast an analogous reaction in 1,2-dimethoxyethane (dme) gives the organoaluminium complex [Al-2(tBu(2)pz)(3)(C6F5)(2)(OCH2CH2OCH3)] in which each aluminium atom has an eta(2)-pyrazolate and a C6F5 ligand and the Al atoms are bridged by an eta(1):eta(1)-tBu(2)pz ligand and a 2-methoxyethoxide ligand. In addition, [Al(tBu(2)pz)(3)] was isolated from the reaction mixture in a different form from that previously reprinted. (c) 2010 Elsevier B.V. All rights reserved.
